영어의 Latin abbreviations

Abbreviation	Latin term	English translation
i.e.	id est	that is
e.g.	exempli gratia	for example
cf.	confer	compare
et al.	et alii	and others

In particular, the abbreviations i.e. and e.g. are often mistakenly interchanged, and cf. is often misused to mean “see” when it actually means “compare”. Also, note that there is no period after “et” since it is not an abbreviation.
